Gradius Collection is an arcade game with action and shooter elements from the developers of Konami Computer Entertainment Tokyo, Inc.. The game is published by Konami Digital Entertainment, Inc.. Gradius Portable is an alternative name for Gradius Collection. For some reason the game has not yet been released on PC. It seems that the Gradius Collection turned out to be complete crap. This is evidenced by the low ratings on the Metacritic service.
